the visible V-8.....geez what a PITFA to assemble that thing... Mine... all the pushrods were too short. so i had to glue on "shims" so they would actually open the valves... wish I still had that I recall getting MY first wrench n plier set 5th grade! My dad allowed mom to get it... Day after Christmas back to the store (SEARS) to be returned...."You said you were going to buy some tools...not TOYS". Then went and bought my first BLACKHAWK tools Wish i still had those TOO!
